Equipment features:
1. Heating wires are distributed in a circular pattern inside the furnace, surrounding the furnace tubes 360 degrees to improve temperature uniformity inside the furnace;
2. High purity Al2O3 fiber refractory insulation material has superior insulation effect and effectively reduces equipment power consumption;
3. The furnace body adopts a double-layer air-cooled structure process, which helps to reduce the surface temperature of the shell;
4. Adopting intelligent PID fuzzy temperature control, with a 7-inch touch screen for centralized control, it can intuitively display the "time temperature" curve;
5. Adopting an integrated water-cooled flange to prevent the flange from overheating and damaging the sealing ring, fully ensuring the sealing performance of the equipment;
6. Using independently developed electromagnetic suspension release technology to achieve rapid quenching treatment of materials;

Pressure measurement and monitoring

Using a mechanical pressure gauge, the outer shell of the gauge is an airtight structure, which can effectively protect the internal components from environmental impact and debris intrusion, and has strong corrosion and high temperature resistance.

Gas supply system

The gas flow rate is controlled by a float flowmeter, which is integrated with the equipment and has undergone leak testing before leaving the factory.

Equipment usage precautions

1. When the furnace temperature of the equipment is ≥ 300 ℃, it is prohibited to open the furnace to avoid injury;
2. When using the equipment, the pressure inside the furnace tube should not exceed 0.125MPa (absolute pressure) to prevent equipment damage caused by excessive pressure;
3. When used under vacuum, the operating temperature of the equipment shall not exceed 800 ℃.
4. The internal pressure of the gas supply steel cylinder is relatively high. When gas is introduced into the furnace tube, a pressure reducing valve must be installed on the cylinder. It is recommended to purchase a small pressure reducing valve for testing, with a range of 0.01MPa-0.15MPa, which will be more precise and safe to use.
5. When the temperature of the furnace body exceeds 1000 ℃, the furnace tube cannot be in a vacuum state, and the air pressure inside the furnace tube must be equivalent to atmospheric pressure and maintained at atmospheric pressure;
6. Long term use temperature of high-purity quartz tube ≤ 1100 ℃
7. It is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube during heating experiments. If it is necessary to close the gas valve to heat the sample, it is necessary to always pay attention to the reading on the pressure gauge. The absolute pressure gauge reading should not exceed 0.15MPa. The exhaust end valve must be immediately opened to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
